INSTALLATION OF THE ARCTIC AIR OPTION
Introduction
This is your guide to installing the ARCTIC AIR air conditioning option package to your Glacier
Bay refrigeration system.
The addition of ARCTIC AIR to your system allows your refrigeration system components to
automatically serve "double duty" as an efficient air conditioner for the 22-23 (average) hours per
day when they aren't needed for refrigeration. Because of our innovative thermal storage
technology and outstanding efficiency, a Glacier Bay refrigeration system generally needs to run
only about 1/2 to 2 hours per day to handle your boat's refrigeration needs. This means that the
compressor and other major components of the system are "off" up to 97% of the day. It is
during this "off" time that the ARCTIC AIR option automatically puts the refrigeration system back
to work to provide air conditioning for the cabin.
Far from just a convenient add-on, the ARCTIC AIR system is a powerful, reliable and unusually
efficient air conditioning system.
Locating the Blower Unit(s)
The ARCTIC AIR blower units are designed primarily to be used in non-ducted type installations.
However, where required, a limited amount of ducting can be used to route either the intake or
discharge (fan reversed) air flow.
Physical location
There are two theories on the placement of AC blowers on board. Conventional wisdom points
out that, since hot air rises, it is usually desirable to try to mount the blower (intake and
discharge) as high in the boat as possible. However, some experienced installers point out that
most boats have a great deal of natural air circulation at the top of the cabin and the blowers
placed high become very inefficient. In our experience there is truth in both of these positions
and it really comes down to the layout of the particular vessel. Many times an “ideal” position
simply isn’t possible due to space limitations. While many owners prefer to adapt existing
cabinets and storage spaces, don't rule out the construction of custom enclosures for your
system. This can expand your options when it comes to blower placement.
The illustration one the following page suggests some possible locations on a typical vessel.
Remember to consider the following items when choosing your location:
1. Tubing runs - You will want to route your copper tubing in an aesthetically pleasing manner.
2. Blower adjustment access - The blowers on multi-blower systems have an access cover
(square with four screws) on the top left side (as viewed from the front). Allow at least 5"
clearance to access the adjustment under this plate. Note that the blowers on single blower
systems do not have or require this adjustment.
3. Condensate drain - Condensation can produce several quarts of water per hour. Most
owners of fiberglass vessels route the condensate tubes directly into the bilge. Some owners,
particularly those with wooden and metal boats, will want to use a separate, easily emptied
container.
4. Air throw - ARCTIC AIR blowers have an average air throw of 12 ft. in most non-ducted
installations.
